Frequency and Severity of Allergic Reactions to Non‐Mandatory Labelled Allergenic Foods—Data From Two Large European Cohorts

Non-mandatory labelled allergenic foods were identified to cause severe allergic reactions in two large European cohorts. The frequent involvement of sunflower seed, pine nut, pea and lentil, but also rising numbers of reactions to fenugreek and pumpkin seed, indicates their potential risk. These allergenic foods warrant close monitoring and consideration in future allergen labelling revisions.
